$24.00, and fixed costs are $863,000 per year. The tax rate is 21 percent, and we require a return of 11 percent on this project a. Calculate the base-case operating cash flow and NPV. Note: Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16. b. What is the sensitivity of NPV to changes in the sales figure? Note: Do not round intermediate calculations and round your answer to 3 decimal places, e.g., 32.161. c. If there is a 400 -unit decrease in projected sales, how much would the NPV change? Note: A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16. d. What is the sensitivity of OCF to changes in the variable cost figure? Note: A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answer to the nearest whole number, e.g., 32. e. If there is a $1 decrease in estimated variable costs, how much would the OCF change? Note: Do not round intermediate calculations and round your answer to the nearest whole number, e.g., 32
